The Use of Prepayment Energy Meter and Its Advantages over Induction Meter

Ⅰ. How does a prepayment energy meter operate and how is it installed?

Prepayment energy meter has become more common as society has progressed. They are now found in office buildings, flats, schools, and shopping malls. Today, we will go through the installation and operation of prepayment energy meter in detail.

1. Installation

Install the prepayment energy meter vertically, and then open the energy box lid. Finally, wire each end to the power supply according to the wiring diagram.

2. Operation following the acquisition of electricity

Users must first purchase electricity in advance, then take the IC card  and enter it into the meter in the direction indicated by the arrow on the card. The monitor first displays F1, then displays the purchased electricity, and then stably displays F2.

The display will then indicate the current remaining power as the sum of the original remaining power plus the freshly acquired power, at which time the IC card may be removed and the display will turn off. Smart prepaid electricity meter pulse lights flash when the user uses electricity.

3. Warnings to the user purchasing the electricity

The prepayment energy meter automatically reduces the quantity of power purchased based on the user's electricity usage during regular use.

When the remaining power reaches 10 degrees, the user will be reminded to purchase electricity by automatically pulling the switch. At this point, the user must enter the IC card into the meter once to restore power. Once the remaining power reaches zero, the power will automatically turn off.

4. Check the remaining power

The preypayment energy meter's display is not illuminated. When the user inserts the IC card into the prepayment energy meter to check the remaining power, the display will indicate F1 bought power is zero, F2 remaining power, and the display will close when the card is withdrawn.

Ⅱ. Three primary benefits of a prepayment energy meter over an induction one?

In today's culture, no one can live without the use of an electrical meter. The classic induction meter was used in the past, but as science and technology progressed, the electronic prepayment energy meter progressively replaced the mechanical meter and has become a commonly used electricity meter.

Electronic components used in professional prepayment energy meters are designed in such a way that they outperform mechanical meters in many ways. What are the benefits of prepaying for energy?

1. High precision

Traditional induction meters, which develop slower and slower owing to mechanical wear and tear faults and have an error range several times larger than the prepayment energy meter, are also significantly less accurate.

It can even surpass the acceptable range after several years of usage. The error range is relatively narrow and the operation is always stable since the prepayment energy meter is electronic.

2. Low power consumption 

The power consumption per meter is usually very low due to the electronic design of the smart prepaid electricity meter, saving 2 to 3 times the power consumption compared to a normal induction meter. And the average power consumption per household will be even lower for a multi-user centralised prepayment energy meter.

3. Multi-function

The prepayment energy meter's electrical technology allows it to be connected to a computer via the appropriate communication protocol and to control and manage the hardware via the appropriate software.

As a result, a prepayment energy meter is significantly smaller than an induction meter, and it can perform a variety of activities such as remote control, detection of malicious loads, anti-theft, and prepayment, among others.

The prepayment energy meter eliminates the need for manual meter reading. The prepayment energy meter is a better solution for issues such as temporary usage, dispersed owners, dispersed users, or frequent power bill default, and it is a sign of social development and increased living conditions.
